Be it known that we, EUGENE D. C. BAYNE and LAWRENCE A; SonERs, citizens of the United States, and residents of Cleveland, county of Cuyahoga, State of Ohio,'have in- Vented certain new and useful Improvements the Component and exact description, such as'wlll enable others skilled in the art to which it apper ties those of extreme threads must be coated tains to make and use the same.

The objects of he invention are to provide a thread which is to be incorporated in a 'fab-' ric designed to include in itsvarious propere tensile strength combined with perfect flexibility and freedom from frictional contact of the component threads, and of the fiber strands of the thread itself, whereby the fabric is rendered also more durable under all kinds of flexure. To provide threads of this charactei' the component strands thereof must be coated exteriorly with a coatin of non-fibrous .and tenacious material, an also the completedwith the same. or similar material. before they are .unitedtogether to form the fabric, so that not only the several strands composing! the individual threads will be coated and rendered wholly out of contactwith each other in the finished threads,.but also the individual threads will I be coated and separated out of contactwith each other in the fabric and therefore incapable of frictional contact upon each other. To prepare a thread having these capabilities an qualities, it is first essential that the fibrous strands thereof if already twisted together should first be momentarily se arated and immersed within the vulcanizab e co'ating material and as soon as the material has been dried or partially dried thereon the strands are umted to form the complete thread, or' strands which are separate may first coated, and then united together.

thread is then exteriorly coated with the same non-fibrous compound to as'great a thickness as the characterof'the-particular fabric for which it is to be used; may require,

,q'and the final coating after being driedis passed between grooved rollers to compress and sohdlfy, as well as to give.- a erfect cyhndncal shape to the coating. The coating smooth surface without rubber or other ela;ti'c and vulcanizablemas terial so that it can be vulcanized when it is incorporated within the fabric.

The india rubber coating retains a sticky surface until vulcanized, and hence the threads are adapted to be severally laid in their exact positions, and with their cylindrical surfaces in accurate relation to each other, and to adhere together, and pressure is also provided at thetime of laying the threads to produce "a perfectly regular, ine ualities of any ldnd. .The perfect cylindrica surface is also conducive to that effect.

The construction of the fabric is described in an accompanying application, Ser. No. 37 0,139-of which this is a division.

In the accompanying drawings, Figure 1 1s a view of a portion of a completed thread; Fig. 2. is an enlarged transverse section thereof; Fig. 3 shows a flat fabric composed sexof two layers of parallel coated threa tended at light angles to each other.

The threads of one transverse layer cross the threads of the other transversela or at an angle, if more than one layer is emp oyed.

In these views, 1 is the thread, 2 the separated fibrous strands thereof, 3 the coating thereon, 4 the outer coating upon the thread composed of united strands.

It is obvious that a finished thread consisting of two or more n'brous strands can be momentarily untwisted and fed to the 'bath and united into a thread, or a. number of fibrous strands can be fed to the bath before they are united into a thread. 1

We. believe ourselves to be the first to make a finished thread (linen preferred) consisting'oftwo or more united strands and to treat the fibrous strands thereof and thread in the manner herein described for the purpose of manufacturing a fabric in which the threadsadhere together without-weaving.

ioo

.. It naturally follows thatif the strands become saturated with the rubber or analogous solution employed to coat them (which would certainly occur if they were free from impurities such as oil or wax) it would add materially to their flexibility when united to form a thread and when afterwards incorporated in a fabric.

Havmg described the invention, What We claim as new and desire to secure by Letters Patent is 1. A thread for an unwoven fabric, comprising fibrous strands twisted together, such fibrous strands being momentarily unform the thread, and the twisted thread having a coating of cylindrical and non-fibrous and adhesive material colnpresscd thereon.

L with a non-fibrous and flexible material, the

twisted and coated with a non-fibrous vulj canizable substance having a sticky surface prior to retwisting, and the retwisted thread provided with an exterior coating of the same material.

, 2. A thread for an unwoven fabric, comprising a series of fibrous strands united together, a separate coating upon each strand of a non-fibrous and tenacious material and an exterior coating of the same material upon the'twisted thread.

3. A thread for an unwoven fabric, comprising a plural number of fibrous strands united together, each strand having a coating thereon of non-fibrous and adhesive ma terial the said strands adhering together to said coatings upon said strands and threads being adhesive and vulcanizable.

5. A thread comprising fibrous strands grouped together, said strands being each saturated and coated with anon-fibrous flexible material and the completed thread also coated with a non-librous and flexible material, the said coatings upon said strands and threads being adhesive and vulcanizable.

In testimony whereof we hereunto set our hands this 22nd day of June, 1907, at Cleveland, Ohio.
